PURPOSE: To investigate the accuracy of biometry and intraocular lens (IOL) power calculation using partial coherence interferometry (IOL Master(R)) in highly myopic patients with axial lengths of 26 mm or greater. METHODS: Patients with axial lengths equal to or greater than 26 mm who had undergone cataract surgery were enrolled. IOL power was calculated using IOL Master and/or applanation ultrasonography with the SRK/T formula. Twenty-seven eyes using both IOL Master and applanation ultrasonography were included in a paired group, and forty-eight eyes using the IOL Master only and twenty-five eyes using applanation ultrasonography only were included in unpaired groups. The differences between the predicted refraction and the actual refraction were compared and analyzed. RESULTS: In the paired study, the axial lengths in patients using IOL Master (29.14+/-2.32 mm) were significantly longer than those of patients using applanation ultrasonography (28.57+/-2.23 mm) (p<0.05). The mean absolute error (MAE) of the IOL Master and applanation ultrasonography groups were 0.62+/-0.58D and 0.87+/-0.49D, respectively (p>0.05). In the unpaired study, the MAEs of the IOL Master and applanation ultrasonography groups were 0.61+/-0.61D and 0.65+/-0.63D, respectively. CONCLUSIONS: In eyes with axial lengths of 26.0 mm or greater, the accuracy of IOL power calculation with IOL Master using the SRK/T formula was comparable to that with applanation ultrasonography.

The occurrences of thyrotoxicosis in patients with myasthenia gravis have been reported before the knowledge of the pathogenesis of the two disease. Thytotoxicosis is known to occur in 3 to 6 percent of patients with myasthenia gravis and myasthenia gravis occurs in only a fraction of 1 percent of the thyrotoxic populatian. Myasthenia gravis is currently considered as a systemic autoimmune disorder of acetylcholine receptor and often presented with other autoimmune diseases such as SLE, Rheumatoid arthritis. We experienced a 18-year-old woman who presented with graves disease and isolated ocular myasthenia gravis. Chest CT didnot reveal enlarged thymus. The usual treatement of myasthenia gravis associated with thymtoxicosis consists of medical control of the thyrotoxicosis, then thymectomy and later subtotal thyroidectomy. Her ptosis and thyrotoxicosis have improved after the medicatian of anticholinesterase and propylthiourecil. A case of ocular myasthenia gravis with Gravesdisease was experienced, so we reported the case with a brief review of literature.

This article describes the normal range of orbital linear dimensions (eq. orbital breadths, orbital height, orbital depth, interorbital breadths and biorbital breadth) and orbital indicies. One hundred and eighty-seven Korean skulls from grown-up individuals are studied with analysis for the purpose of evaluating anthropometric characteristics of Korean orbits. The results are compared to previously published data for modern Korean skulls. The width of the orbit is larger on the right side than the left and sexual difference was also shown. On the other hand, the heights of both orbits are much the same. Consequently, there is a slight tendency that chamaeconch is met with more frequently on the right side, whilst hypsiconch on the left side. The orbital depth is larger on the right side, however, depth index did not show any side difference. There are sexual differences on the biorbital breadth and upper facial breadth but not on the interorbital breadth on the basis of dacryon. These results represent the asymmetry of Korean orbit and that measurement on both sides must be necessary for anthropological comparison.

BACKGROUND: Postpartum thyroiditis(PPT) is one of syndromes of thyroid dysfunction that occurs in the first year after parturition. Reported incidence of PPT is 3.9-8.2% of postpartum women in several studies from different countries. The fact that 52-100% of patients with PPT have thyroid autoantibodies, and that lymphocytic infiltration of thyroid gland is the characteristic pathological feature of PPT suggest that PPT is an autoimmune disease. High iodine intake in short term period is known to aggrevate the experimental autoimmune thyroiditis. This study was performed to investigate the incidence and clinical features of PPT in Korean postpartum women who usually ingest excessive amount of idine in immediate postpartum period and to investigate the predictive value of thyroid autoantibodies in the development of PPT in them. METHOD: Between March 1996 and February 1997, 99 women without previous history of any thyroid disease who delivered babies at Boramae hospital were enrolled. Thyroid function parameters(T3, T4, free T4, TSH), thyroid autoantibodies(anti-microsomal antibody, anti-thyroglobulin antibody) and urinary iodine excretion were measured prospectively before and 1, 3 months after delivery. Dietary iodine intake during postpartum period was evaluated by questionnaire, and clinical parameters were followed up. RESULTS: During 3 months of observation, PPT developed in 8.1%(8/99) of postpartum women. Five cases had typical course having thyrotoxic phase and the other 3 cases had hypothyroid phase without toxic phase. However, only one of those required thyroid hormone replacement therapy in the latter group. There were no differences in age, baseline thyroid function parameters, parity, percent cases with family history of thyroid disease between those developed PPT (n=8) and those did not develop PPT(n=91). Duration of high iodine intake(3.8 +- 0.5 wk. vs. 3.7 +- 0.8 wk., p>0.05), total ingested amount of high iodine diet(77 +- 28 vs. 79 +- 24 bowels of miyokguk, p)0.05), and the urinary iodine excretion(1.9 +- 1.4 mg/g creatinine vs. 3.7 +- 3.7mg/g creatinine, p0.05) at 1 month postpartum were not different between two groups. Of 99 total subjects, anti-microsomal antibody(AMA) was present in 13.1%(13/99) before delivery in their sera. Positive predictive value of the presence of AMA before delivery in predicting the development of PPT was 30.8%. CONCLUSION: The fact that incidence of PPT in normal Korean postpartum women who usually have high iodine intake in immediate postpartum period is not higher than those of other countries, and that there was no difference in the amount of iodine intake between those developed PPT and those did not suggest that high iodine intake in immediate postpartum period do not influence on the incidence of PPT. The presence of AMA before delivery had low specificity in prediction of development of PPT, so the measurement of AMA seems not to be a useful screening test.

Orphan nuclear receptor estrogen-related receptor γ (ERRγ) regulates cell growth and tumorigenesis in various cancers. However, the clinical relevance of ERRγ to hepatocellular carcinoma (HCC) remains unclear. Here we examined the clinical significance of ERRγ in HCC and its potential as a therapeutic target. ERRγ levels in tissues from completely resected specimens from 190 HCC patients were examined immunohistochemically and their association with clinical stage and pathological grade was analyzed. Small interfering RNA (siRNA)-mediated knockdown of ERRγ (siRNA-ERRγ) or an ERRγ inverse agonist, GSK5182, were also used to examine the effects of ERRγ inhibition on the proliferation and growth of a human hepatoma cell line, PLC/PRF/5. Immunohistochemical analysis revealed that tumor tissues showed higher levels of ERRγ-positivity than adjacent non-tumor lesions. Tumors showing high levels of ERRγ immunoreactivity also had advanced tumor node metastasis (TNM) and Barcelona Clinic Liver Cancer stages and a higher Edmondson–Steiner grade. In addition, high-level expression of ERRγ in tumors of advanced TNM stage correlated with poorer overall survival. Treatment of PLC/PRF/5 cells with siRNA-ERRγ or GSK5182 inhibited proliferation through G1 arrest, increased expression of p21 and p27 and decreased expression of phosphorylated retinoblastoma protein. GSK5182-induced reactive oxygen species also suppressed the proliferation of PLC/PRF/5 cells. The present study showed that ERRγ expression is clinically significant in HCC; therefore, it can be considered a biomarker for HCC diagnosis. Moreover, the results provide a rationale for the use of ERRγ inhibitors such as GSK5182 as potential therapeutic agents.

Sialadenosis is a unique form of non-inflammatory, non-neoplastic bilateral salivary gland disorder characterized by recurrent painless swelling which usually occurs in parotid glands. Alcoholism is one of the main causes of sialadenosis along with diabetes, bulimia, and other idiopathic causes. The prognosis is verified according to the degree of liver function. We present a case of a 46 year-old man who had alcoholic fatty liver disease diagnosed as alcoholic sialadenosis based on clinical points of recurrent bilateral parotid swelling after heavy alcohol drinking, computed tomography, and fine-needle aspiration biopsy. After stopping alcohol drinking and treated with conservative treatment, he got improved without specific sequela.

OBJECTIVE: The purpose of this study was to self-management asthma including symptom, medication, and to prevent the exacerbation of the condition using the Personal Asthma Management System(PAMS) which was developed based on Personal digital Assistant(PDA). METHODS: A development tool of the PAMS was EVC(Microsoft Embadded Visual C++). The system contents referred to workshop report of the Global Initiative for Asthma, on-line lecture of the Korean Society of allergology and Korea Asthma allergy Foundation, asthma-related web-sites. RESULTS: The PAMS was implemented with four main menus: personal information, symptom, medication management, and self care. The patients input their daily condition, and this data will be used in the successful prevention and management of asthma exacerbation. This real-time nature of PAMS is its primary advantage over other retrospective computing system for reducing the effects of forgetting, so this information will be useful in classifying of asthma severity. CONCLUSION: The PAMS can be contributed to aid self-management of asthma and effective treatment by attending physician.

PURPOSE: Epidural hematoma (EDH) in newborn is very rare, but when it occurs it is usually due to birth injury. We have evaluated the incidence and clinical features of EDH related to birth in newborn. METHODS: We analyzed medical records of 12 newborns diagnosed with EDH at Cheil General Hospital and Women's Health Care Center from January 2000 to December 2015 retrospectively. RESULTS: The incidence of EDH related to birth was 0.01%, occurring in 1 of 10,000 live births. Of the total 12 cases, 10 occurred in male and 8 in vaginal delivery. Among them, 11 infants had evidences of birth injury. Clinical presentation was nonspecific: only 1 infant had neurologic symptoms. The temporooccipital area was the most frequent location of EDH. The median size of EDH was 3.2±0.8 cm in length and 1.2±0.7 cm in depth. Mass effect accompanied with midline shift on radiologic imaging was shown in one case. Surgical drainage was needed only in one infant with neurologic symptom and mass effect on radiologic imaging, while the others were treated conservatively. CONCLUSION: Neonatal EDH related to birth was treated conservatively in most cases. The radiologic mass effect and neurologic symptom should be considered as indication for surgical intervention.
